Current DAS only have one implementation supporting Relational Database
(RDB). In order to allow DAS to support multiple implementations (e.g LDAP
DAS proposed by Ole Ersoy :
http://www.mail-archive.com/[email protected]/msg13395.html) I would
like to propose some changes on the DAS project structure as explained below
:
1.Create an das-api project, and move the general interfaces, and maybe part
of the config model to this project as well.
2.das-rdb and das-ldap would depend on this common das-api project
3.Enhance the factory pattern to handle multiple das implementations,
probably implementing the service locator pattern to handle the multiple
implementations.
The new programming model would probably look like :
DASFactory factory = DASFactory.getInstance("RBD")
DAS rdbDAS = factory.creDas(...)
Current unresolved issue that I have is regarding the config mode, i think
this might be specific to each implementation, and I need to see what's the
best approach to handle this on the das-api.
I should have something in my sandbox over the weekend.
Thoughts ?
